Oh B & C are practically neck and neck all of the sudden. Could the moss be hindering the growth of B?



Yes.

But not sure about the moss it isnt tightly packed and is quite loose. I found that the smaller dense moss that consolidates the surface tends to have an effect on VFT growth.

Also what is also interesting is the consistantly redder traps of the one in perlite. I dont think it is the perlite itself that is affecting the colour as I understand it is an expanded volcanic glass an inert. I think it is possibly due to the slower growth of this plant, so giving more time for the colour to develop before the trap reaches maturity, possibly.

I think you need to use he light switch button at he top of the edit window to select code. Works for me.

Update.
This will be the last photo of this experiment.

Conclusion
VFTs grown in a mix of peat and pine needles appears to grow better than in the common mix of perlite and peat. Best growth occured in a 50:50 mix. However the experiment was only conducted on single plants for each medium type. A larger group of plants grown in each medium would need to be tested to statistically verify this finding.

Pine needles certainly do not harm the VFTs and can safely be used as a substitute for perlite. If indeed the pine needles are resulting in better growth of the plants then possible reasons for this are given below.

1) It is possible that the needles maintain the acidity of the peat creating a longer lasting, more stable acidic environment around the roots. Unfortunately I did not have any means o testing the pH to confirm this.

2) The pine needles might be slowly decomposing releasing small amounts of nutrients into the peat, sufficient to benefit growth but too low to harm the plant.

3) The filamentous nature of the needles may create better aeration of the peat. It was noticed that the pine needles medium did not compact as much as the perlite medium and remained more more spongy to the touch.

Do you have some new pictures Mantrid? Would be good to see how the experiment is getting on.

Mine is still in the original pine needles. Think this is the third season and the plant has been outside year round. Been a poor year for VFT outside this year, buts its still put out some small traps and flower stalks

Yes it was a bad start but the hot sunny weather over the last few weeks with some recent rain means things are picking up nicely and colouration is getting better

I collected someLarch needles a few weeks ago. When I scraped the needles up I found that the rotted down needles has produced a brown material a bit like peat so I collected some of this also. I made up a compost mixture of 1 part Perlite, 1 part grit sand (J Arthur Bowers) and 1 part Larch material - mostly the brown "peat".

I planted up some straggly Venus Flytraps in it that I wasn't bothered about losing and three or four weeks later they have put on some growth and certainly are not showing any signs of distress.

The pic is of the plants just after I potted them up (10cm pot).

The pine needles in my original plant have all rotted down and the VFT is still growing fine, albeit a little slowly due to inclement weather.

My experiment has settled/sunken down in its pot due to needle decomposition. I shall have to bottom dress the pot next season to raise the level of the plants up to the top of the pot.

Mine has never been repotted since my original picture post in this topic in 2011. The VFT doesn't look the best this time of year, as it grows outdoors year round. You can see that the medium level has dropped.

As I am in Lebanon now, I have bring with me some tuberous drosera, no peat here so I have use pine needles, burning pine wood and some sand. It work good. Posted Image Posted Image Posted Image

I personally think that pine needles are quite a viable alternative medium and I have started to add them to my normal mixes. I have had less issues with them as a CP medium than I have had with coir and I don't have to worry as to how they have been washed.
